Whether it's a single-pitch or hipped roof, the limit for additional waterproofing is a 22° pitch for most types of shingles. Below this level, additional waterproofing is required. In this case, the slope of a tile roof can be at least 7 °. Below that is a special sealed flat roof.
According to an architect in my family (but also retired), flat roofs are ALWAYS problematic, and she would NEVER build a flat roof.
From my office, I can see our neighbor's roof (a flat roof bungalow built around 1980) where there is always water on the roof. Even if it has been dry for 2 days. Last summer he covered the roof with new asphalt sheets.
